MAX7316 Overview
The MAX7316 serial interfaced peripheral provides microprocessors with eight additional I/O ports plus one output-only port and one input-only port. Each I/O port can be individually configured as either an open-drain current-sinking output rated to 50mA at 5.5V or as a logic input with transition detection. The output-only port can also be assigned as an interrupt output for transition detection.
